CHICAGO — Blurred video images released after a bank robbery showed three men bursting into the lobby with guns drawn, wearing black shirts and white gloves.

Their faces covered with what appear to be stocking caps, the men point their guns at customers and employees. In a still image, a robber stands on a counter with what looks like a bank drawer in his hand.

Authorities released the images from surveillance cameras at a South Side bank on Wednesday, a day after the heist that killed a 23-year-old teller and wounded a guard and a customer.

Investigators continued their search for the men Thursday, FBI spokesman Ross Rice said.

In the images, the men are completely covered and seem to be dressed almost identically, with white athletic shoes, blue jeans and black long-sleeved shirts.

The wounded guard, Earl Coleman, told the Chicago Sun-Times and the Chicago Tribune that the men wore bulletproof vests and that he shot one in the back and shoulder.

Investigators scoured a stolen getaway car and an empty cash box found inside it Wednesday as they pleaded with the community for information that could help find the gunmen. The FBI was offering a reward of up to $50,000.
